A new service called the Las Vegas Wedding Wagon is currently operating in Sin City, offering couples a traveling minister who is able to immediately drive on over and marry couples at their preferred locations.

The 15-minute 'sidewalk ceremony' service, priced at $99, has married four couples since it launched last week and even provides a witness.

The service also includes five 'candid' photos that are emailed to the couple once the ceremony is completed.

A souvenir T-shirt – priced at $20 for one and $35 for two – is also available through the service.

The one thing it doesn't provide is a marriage license, which is required for the ministers to conduct a ceremony.

The two men behind the service, who were both ordained online, were inspired to create the Wagon after learning of the Hangover Heaven bus, a automobile that travels the Vegas strip, offering medicines and vitamins to those who partied hard the night before.

Unique: The service can travel anywhere and has married four couples since it launched last week

Andy Gonzalez and James Cass had originally come up with the idea last year.

Mr Gonzalez told ABC: 'We both saw the potential. There could be real money here.'

But when the Hangover bus was unveiled, the men knew they were onto something.

'We were saying, “should we pull the trigger” and then we saw that story about the Hangover Bus, he recalled. 'When we saw that, we said “anything is possible”.'
